2 Claims. '(01. 197-126) My present invention relates to devices for controlling webs, and has more particular reference to a structure for use in connection with the carbon or manifolding sheets used in a machine 5 wherein several strips of papers are moved across a writing bed with carbon sheets interleaved to produce multiple copies and after which the paper strips are severed in the desired lengths at the front end of the machine. The present improvements are especially adapted for use in a flat-bed typewriting machine in which the paper strips are preferably maintained in position at the discharge end of the machine by a clamp and in which means are provided for adjusting registering and arresting the feed of thepaper strips through the medium of apertures arranged in spaced relation in the strips preferably between or at an end edge of each ticket printed upon the paper strips. I

In devices of the above character, it has been the usual practice to mount the carbon or manifolding sheet in the form of a multiple-sheet roll upon a longitudinal side of the machine outside the platen, and to interleave the sheets in a direction transverse to the length of the paper strip. When it is desired to change the carbon, the end edge is pulled out while a fresh surface or surfaces are interleaved and the worn portion or portions are torn oh. This is objectional be- 80 cause of the fact that the movement of the carbon sheets across the paper strips frequently mars or soils the surfaces of the same as well as the operators hands, and; in addition, thereto it is a more laborious proceeding than with my present structure.

My improvements'contemplate the ready feed or replenishment of the carbon or manifolding material without liability of damage or soiling sheets or strips. Other objects of my invention reside in providing a device of the character herein described that is dependable in operation, and which 7 is constructed so that it may be readily installed in a machine that is in use. The mechanism is novel and simple in construction, and is easy to operate, and on account of its simplicity and its small number of parts may be manufactured and sold for a moderate price. The device I have designed also efiects a considerable saving of time for the person using the same as the operation of the parts are to a large extent automaticin performing their functions.

I prefer to carry out my invention and to accomplish the objects thereof in substantially the manner hereinafter described and as more par-- ticularly pointed out'in the claims, reference 1,693,035, granted November 27, 1928, for Regisbeing madeto the accompanying drawings that form a part of this specification.

In the drawings:

- Figure 1 is a top plan of my invention installed upon the writing-bed frame of a well-known flatbed typewriting machine, a portion of the platen being omitted or broken away.

Figure 2 is a vertical longitudinal section on line 22 of Figure 1, looking in thedirection of the arrows.

Figure 3 is an enlarged view of a fragmentary portion of the structure shown in Figure 2.

The drawings are, in a sense schematic, for the purpose of illustrating a typical or preferred form in which my improvements may be constructed, and in said drawings I have employed similar reference characters to designate like parts wherever they appear throughout the views.

My invention is shown in connection with the platen of the well-known Elliott-Fisher flat-bed typewriting machine, the typing mechanism and traveling carriage being omitted for clearness. The platen frame consists of parallel side-rails 10 that provide a track for the carriage and are connected at their front or forward ends (nearest the operator) by cross-piece 11 and between the rails -or arms, back of the cross-piece, the flat platen 12 is'mounted. A supplemental frame is removably mounted upon the 'side rails at the rear of the platen and consists of longitudinal bars 13 that are connected to the rails by hangers 14. A roll or rolls of paper are journaled in pendent carriers 15 at the rear ends of bars 13 and the paper strips 16 (of which two are shown in Figure 2) are led up over guide-rollers 17 and between vertically spaced guide plates 18 where the apertures in the paper'strips are engaged by the spring-engaged pins 19 of the 'paper control mechanism such as disclosed in my Patent No. tering Paper Webs. These pins are carried by a rock-shaft 19 and tend to be thrown rearwardly by a spring 19 in the manner described in said patent, thus drawing the webs 16 rearwardly (to stretch them taut on the platen 12) The carrier for the carbon is positioned intermediate this control mechanism'and the rear end of theplaten'lZ. The platen is shown brokenly, only its front and rear end-portions appearing. After passing the carbon sheet carrier, the paper 5 strips are led along the platen to its forward edge where said strips are maintained upon pins or stops 20 by a liftable knife to tearing blade 21, the pins or stops entering the adjacent apertures in the paper strips. The carbon carrier consists frame.

of a frame having a pair of parallel side bars 22 extending longitudinally alongside the side rails 10 of the main typewriting frame and are supported by means of posts 23 arising from the side bars 13 of the supplementary frame, which posts have laterally disposed headed studs 24 projecting horizontally towards each other through longitudinal slots 25 in the side-bars 22, so that the carbon carrier frame may be reciprocated or slid longitudinally independently of the main and supplementary frame and the paper strip. Cross rods in the form of rollers 26 connect the side bars near their upper edge and similar cross rods or rollers 27 connect said bars adjacent their lower edges. The carbon sheets are preferably in rolls 28, one sheet to each roll, and the cores 29 of the rolls have spindles that are mounted in the bottoms of vertically disposed transverseslots 30 extending into the side bars 22 from their upper edges, and in order to maintain the rolls against accidental rotation I place washers 31 at the ends of the cores that are frictionally pressed against the edges of the carbon rolls by coiled springs 32 that are interposed between the washers and the adjacent surface of the side bar 22. For the purpose of reciprocating or bodily moving or sliding the carrier frame, there is provided a rock-lever 33 pivotally mounted at its lower end on a pivot pin 34 projecting from an adjacent stationary portion of one of the other frames which lever is provided with a lateral projection 35 that enters a slot 36 in the adjacent portion of one of the side bars 22 of the carbon carrier At its upper end lever 33 has a pivotal connection with an operating rod 3'7 that extends to the forward end of the main frame past the cross-bar 11 upon which it rests and has a handle 38 formed in its end by which it may be- 1 grasped and reciprocated to operate the carbon carrier.

When the paper strips are led through or threaded on the machine the strips are supported by the group of rollers 17, from which they pass horizontally forward to their respective rollers 27 mounted along the lower edge of side-bars 22 one of which is adjacent the respective roll 28 of carbon that is to be superposed upon the strip, and the paper strips mounted along the upper edges of said side bars to the platen where they repose flat thereon. The respective carbon sheets pass from their rolls 28. over the rollers 26 in front of and slightly above them and are interleaved between the paper strips on the platen and extend across the same to a point back of the pins-20 that retain the paper strips at the forward end of the apparatus under the clamping knife or tearing blade 21.

During operation, the front ends of the paper strips are grasped and the strips pulled out after lifting the blade 21, the carbon sheets remaining stationary upon the platen. This operation is repeated as often as matter is written on the forms or printed tickets borne by the strips, or

until it is desired to replenish the carbon sheets, whereupon the blade is raised in the regular manner of operation, the paper is lifted from the pins 20 and is then grasped far enough back of its edge to take hold of the adjacent ends of the carbon sheet or sheets. Both the paper strips and carbon sheets are now pulled out until the end of the next printed form or set of apertures is at the pins 20 and the entire set is torn off against the blade. Prior to pulling out the set the handle 38 is pulled forward thus moving the carbon carrier frame forwardly and upon severing the set of paper and carbon the handle 38 is pushed back thus returning the carrier to normal position and permitting the forward edge of the carbon sheet or sheets to clear or move back of the apertures in the paper so that the latter may be then placed upon the pins and the blade 21 lowered to normal position. The thus severed set of paper and carbon may now be separated and the tom-off pieces of carbon thrown away. It

will be appreciated that, during the above-de scribed manipulation of the carbon sheets and paper strips, the pins 19 of the web-control mechanism are retracted out of the paper strip apertures to permit of free withdrawal of the paper in the same manner as when the paper strips are withdrawn after each writing is made on the printed forms.

It will be understood that other mechanism may be utilized in carrying out my invention and that modification may be made without departing from the principle which I have disclosed.

I therefore desire it understood that such changes are fully contemplated as coming within the scope of the appended claims.

What I claim is:-

1. In means of the character set forth; a flat platen; a frame within the front portion of which said platen is mounted equipped with pins in front of the platen and having arms extending rearwardly from the platen; a forwardly and rearwardly movable auxiliary frame mounted between the planes of and carried by said arms; a plurality of carbon rolls supported in said'auxiliary frame; transverse guide-rods forming a part of said auxiliary frame and associated with said carbon-rolls; and means carried by said auxiliary frame for supporting paper webs provided with register-perforations, 'said last-mentioned means being related to the carbon-rolls to permit the paper webs to pass about said guide-rods with the carbon-rolls intervening between the paper webs, the perforations at the front ends of the paper webs serving to engage said regsterpins.

2. Mechanism as specified in claim 1, in combination with spring-actuated means for drawing rearwardly the paper webs while the front ends of said webs are in engagement with the register-pins. I
